Trusted execution environment
The TEE is a standard which creates an isolated environment that runs in parallel with the operating system. It offers a range of security features, including encryption, authentication, and data protection. It also provides a way to pass data from one device to the next.
About Trusted execution environment in brief
A trusted execution environment is a secure area of a main processor. It guarantees code and data loaded inside to be protected with respect to confidentiality and integrity. A TEE as an isolated execution environment provides security features such as isolated execution, integrity of applications executing with the TEE, along with confidentiality of their assets. Only trusted applications running in a TEE have access to the full power of a device’s main processor, peripherals and memory, while hardware isolation protects these from user installed apps running in the main operating system. The TEE is a standard which creates an isolated environment that runs in parallel with the operating system, providing security for the rich environment. It is intended to be more secure than the User-facing OS. ARM TrustZone TEE. is a hybrid approach that utilizes both hardware and software to protect data. It therefore offers a level of security sufficient for many applications. It allows manufacturers to grant access to TEEs only to developers who have a business agreement with the manufacturer.
There are a number of use cases for such tivoization and DRM, such as use as tivoizers and for use in consumer electronics systems in. consumer electronics such as mobile phones, tablets, PCs and smartwatches. The Open Mobile Terminal Platform (OMTP) standard defines TEE in their \”Advanced Trusted Environment: OMTP TR1\” standard. Work on the OMTP standards ended in mid 2010 when the group transitioned into the Wholesale Applications Community (WAC) The OMTP standard is hosted by GSMA. The WAC is a group of leading mobile network operators, operating system developers, application developers, device manufacturers, platform providers and silicon vendors. The group is responsible for the standardization efforts around the Tee. It offers a range of security features, including encryption, authentication, and data protection. It also provides a way to pass data from one device to the next.
